One-stop fulfillment: Siemens Gamesa to supply EnBW Albatros offshore wind power plant as first German full-scope-project

01 June 2017

Complete solution with significant benefits through optimization and synergies

Perfectly aligned technology from generator to grid connection

German debut for Siemens’ compact offshore transformer-module OTM

Following
the 497-megawatt (MW) order for the EnBW Hohe See offshore wind power-plant,
EnBW has also awarded Siemens Gamesa Renewable Energy with the installation of
the neighboring 112-MW-project EnBW Albatros. The scope of supply includes 16
direct-drive SWT-7.0-154 wind turbines on monopile foundations and the grid
connection via a Siemens Offshore Transformer Module (OTM). Siemens Gamesa will
install both wind power plants in parallel. Installation will start in spring
2018. The projects are located 90 kilometers north of Borkum Island in the
German North Sea with water depths of up to 40 meters. The combination of both
projects offers synergies to EnBW in respect to planning, construction, and
during operation. Due to Siemens Gamesa Renewable Energy's complete solution
for Albatros -ranging from turbines to substation technology -the project
benefits from full optimization opportunities: Through the project-specific
approach, all technology components work perfectly aligned so that the risk for
all involved parties is mitigated. At the same time, a bundling of installation
works and a centralized project planning create valuable synergies. After
commissioning in 2019, Siemens Gamesa will initially provide service and
maintenance for the turbines over a period of five years.

EnBW
Albatros is the first German offshore wind power plant that Siemens will supply
as a full-scope project. Furthermore, it includes the entry of the compact
Siemens OTM in the German market. Thanks to focusing on key electrical components
and cutting auxiliary systems, it allows a reduction in weight and size of more
than 30 percent compared to a conventional AC substation. Further cost out is
achieved by using the same foundation type for the OTM as for the turbines. The
ultra-compact design of the platform not only reduces installation costs due to
its low weight, but also reduces service and maintenance efforts. EnBW Albatros
will be connected to the power grid via the Borwin Beta HVDC converter-platform
which is located approximately 25 kilometers away and had been delivered by
Siemens as well.

In the same way as for EnBW Hohe See, Siemens is also partnering with the
Belgian offshore construction specialist GeoSea for Albatros regarding
construction and installation of the monopiles. Again, the extended scope and
the inter-coordinated complete solution including installation works,
construction elements, and wind turbine technology add to the synergies of the
combined projects to enable a highly efficient realization of the projects.
Inter-array cabling and coordination of the construction work remain in the
scope of EnBW.

"EnBW Albatros allows us to demonstrate our broad competence in offshore
projects, ranging from project specific engineering services and the beneficial
combination of power generation and transmission technology to service and
maintenance concepts", states Michael Hannibal, CEO Offshore of Siemens
Gamesa Renewable Energy. "This project has a high relevance for us since
we will turn the 112-megawatt wind power plant into a highly profitable
investment for our customer via cutting edge technology and smart
details."

Siemens Gamesa will showcase their broad solutions for offshore wind projects
at the Offshore Wind Energy 2017 Conference in London (6 to 8 June, 2017) at
their booth N-J 20.
